Picture-in-Picture not working in iMovie 10.3.1
After I upgraded my mac to an M1 pro, my iMovie won't show the picture-in-picture settings. I've tried many things including deleting the preference file by restarting iMovie and pressing CMD+OPT keys, with no success. I would appreciate your help, this is very frustrating, and I need to finish some video editing.
Thanks
Alfredo
